Boldr Energy 4+

(This is a review for the updated app. The old version was poorly designed, but at least occasionally managed to control the heater. The new version? Good luck.)

The app: My needs were few: set the heater to a temperature, turn heater on or off. This app can manage none of this. Instead it presents a needlessly complex way to set up a “smart” schedule. 20 minutes of configuring later, and the heater will turn on - but never turn off. Instead, it runs ceaselessly, cooking the room
regardless of the shut-off temperature chosen.

The sensor (a golf ball-sized piece of plastic garbage, destined to be lost beneath a bookshelf) seems to only register temps in Celsius - even when the heater is configured to work in Fahrenheit. The result is a sensor reading 21 degrees, telling the heater to keep going until it reaches 68. I’d prefer if my room were not 68 degrees Celsius, thanks…

If you’re reading this, you’ve probably already bought the heater and are as screwed as I am. If, by some stroke of luck, you haven’t, save yourself the money and frustration. Any other heater on the market would be better.

My experience has not been as bad as the others — set up took 5 minutes, I find the app simple to use — but the schedule is erratic. It seems to be on another time zone. I didn’t bother putting my home address during set up, and the default one was Lithuania. So at first the schedule was responding to Lithunian time zone (10 hours later). I changed the address, but it didn’t do anything. Then I adapted the heater’s schedule to fit the time zone it thinks it in. That worked partially. But there are random changes in schedule that don’t seem to be time zone related. It starts heating middle of the night, etc. Might try to delete the app and start over.
That said, I can control the temperature manually. That works well.

While the app may need a little more work, the customer service I’ve received from their support team has been fantastic. The issues that popped up with my order were quickly resolved. Have three units in my home and they work great in the areas I put them in.

If you’re a techie, you’ll notice these units have super reliable Shelly controllers internally. Integrated them with my home automation system (Home Assistant) and they work flawlessly.
